Bogdan [553]

Answer:

The rule which allows us to change the sign of an exponent is called the <u>negative exponent</u> rule.

Step-by-step explanation:

Consider the provided information.

The negative exponent rule is the rule which allows to change the sign of an exponent.

x^{-1}=\frac{1}{x}

According to negative exponent rule: A negative exponents in the numerator moved to the denominator and become positive exponents.

If A negative exponents in the denominator moved to the numerator and become positive exponents.

Point A is located at negative 5 over 8 and point B is located at negative 2 over 8. What is the distance between points A and B
ki77a [65]
<h2>Answer:</h2>

Option: A is the correct answer.

A.  negative 5 over 8 minus negative 2 over 8 = negative 3 over 8; therefore, the distance from A to B is absolute value of negative 3 over 8 equals 3 over 8 units.

<h2>Step-by-step explanation:</h2>

The location of Point A is : A(-5/8)

and Point B is located at : B(-2/8)

We know that when two points lie over a number line then the distance between the two points is the absolute difference between the two points.

If A is located at a.

and B is located at b.

Then the distance between A and B is given by:

             |a-b|

Hence, here the distance between A and B is given by:

|\dfrac{-5}{8}-(\dfrac{-2}{8})|=|\dfrac{-5}{8}+\dfrac{2}{8}|=|\dfrac{-3}{8}|=\dfrac{3}{8}\\\\i.e.\\\\\text{Distance between A and B is}=\dfrac{3}{8}\ \text{units}

Answer:

x=30\ degrees

m

m

Step-by-step explanation:

we know that

The sum of interior angles in a triangle must be equal to 180 degrees

so

(x-5)+(3x+30)+(35)=180\°

solve for x

4x=180\°-60\°

4x=120\°

x=30\°
